A
The skin under the eyes is delicate, which is why it sometimes appears sunken and has darker coloring than elsewhere on the face. Aging and health problems play a role in sunken eyes but other factors can contribute, so it may affect younger people as well.
Dehydration
The most common cause of sunken eyes is dehydration, or not having enough water in the body. Consuming too much coffee, soda, and prepackaged drinks may increase production of urine(尿液), which may lead to dehydration.
Vitamin shortages
Shortages of vitamin C, vitamin K, and iron can cause eyes to become sunken. Vitamin C helps with absorbing iron and decreasing bruising(瘀斑), while vitamin K is responsible for blood thickening, causing unhealthy skin. Easy bruising and unhealthy skin will result in sunken eyes.
Weight loss
Most people tend to lose weight in their face first. Sometimes, the weight loss is sudden enough to make blood vessels(血管)below the eyes easy to see, and the skin clear, producing the appearance of sunken eyes. Sudden weight loss may also cause nutritional shortages, which can lead to sunken eyes.
Not enough sleep or poor quality sleep can cause sunken eyes and a person’s DNA or the habit of smoking can also contribute to sunken eyes. Most cases of sunken eyes relate to the quality of an individual’s nutrition and healthy living. When these causes are corrected, sunken eyes can be resolved without further treatment. This means that causes can be avoided or treated in good time to prevent the recurrence of sunken eyes.
